United sovereignty

The EU is made up of 28 sovereign, independent countries that have transferred part of their powers to shared institutions in order to gain the strength and advantages that come with size. The EU system sits somewhere between the federal system of the United States and the intergovernmental cooperation we know from the United Nations.

Achievements and the future

The EU has built a single market for goods and services with more than 500 million citizens who can move freely. It leads the fight against climate change, helps neighbouring countries prepare for membership and is building a common foreign policy to spread European values around the world.

Pooling sovereignty in practice means that the member states delegate some of their decision-making powers to the shared institutions they have created, so that decisions on specific matters of common interest can be made democratically at EU level.

KEY DOCUMENTS

History of the EU treaties

When Robert Schuman proposed integrating the coal and steel industries of Western Europe in 1950, the forerunner of the EU was born – the European Coal and Steel Community. Since then, the EU has regularly updated its treaties to ensure effective policy-making and decision-making.

1951

Treaty of Paris

Establishes the European Coal and Steel Community. Signed on 18 April 1951, it entered into force in 1952. It expired in 2002.

1957

Treaties of Rome

Establish the European Economic Community (EEC) and Euratom. Signed in Rome on 25 March 1957, they entered into force in 1958.

1986

Single European Act (SEA)

Signed in February 1986, it entered into force in 1987. It amended the EEC Treaty and paved the way for the completion of the single market.

1992

Maastricht Treaty

Establishes the European Union, gives the Parliament greater powers and adds new areas of cooperation. It entered into force in 1993.

1997

Treaty of Amsterdam

Signed on 2 October 1997, it entered into force in 1999. It amended and supplemented the earlier treaties.

2001

Treaty of Nice

Signed on 26 February 2001, it entered into force in 2003. It reorganised the EU institutional system in preparation for the 2004 enlargement.

2007

Treaty of Lisbon

Signed on 13 December 2007, it entered into force in 2009. It simplified working and voting methods and introduced the office of President of the European Council.

The EU pioneers — from resistance fighters to lawyers and parliamentarians — were a diverse group of people who believed in the same ideals: a united Europe of peace and prosperity. Many others inspired the European project and worked tirelessly to make it a reality.
